Chuck's Lucky Dice: These are the very dice used by Chuck Plimpton in his tavern games. He is reputed to be quite lucky, and if you doubt that, you should know that Chuck made it back from the land of the dead! He had a set of these dice on his person at the time, and while the dice probably had nothing to do with it, can you afford to take that chance?

Alamanter's Extraspacial Angularities: These dice were created by Alamanter the Violet during his studies in the city of Ciz.

Beware fumbling with these dice!
